RPG and VSAMIO

Jim Snellen All Messages By This Member #57 Hello again, I've been running the RPG examples from Jay Moseley's website (?and been successful, sorta, until example 3.? It reads a card file to create an ISAM file but I thought it would invoke VSAMIO and process the RPG program to work with a VSAM file instead of ISAM.? According to what I've read on his site is should work with COBOL, Assembler, and PL/1 as well.? However, it seems to be on MVS systems only.? Can anyone confirm? I don't remember how to create or process ISAM, it's been way too long!??I downloaded and ran the samples from??without problem and thought I'd play around with Jay's RPG example programs.? BTW, example 2 runs ok except it goes into a loop at EOJ.? I replaced the tape output with SYSLST and it runs fine. I've no idea what's going on.
René Ferland All Messages By This Member #58 Hello Jim, VSAMIO was written for an usage with the COBOL and PL/I (F) compilers of MVT. I was able to assemble VSAMIO on DOS/VS and use it with the FCOBOL compiler of DOS/VS. I have no idea how to use it from a RPG program. As for ISAM datasets, they must reside on a 2314 DASD and they are defined with the usual DLBL and EXTENT statements. The exact syntax is on page 38 of GC33-5376 "DOS/VS System Control Statements". :-) At first sight, I would say it is probably easier for you trying to (recall how to) use ISAM datasets than trying to use VSAMIO with RPG. Cheers, Rene FERLAND, Montreal

A few years ago the company I work for migrated from our mainframe z/OS based platform to an IBM i based platform. I'm thankful that platform now has free-format RPG. I'm not a programmer, but have dabbled a bit with CL and free-format RPG and have no trouble with those. I've tried learning older versions of RPG out of curiosity. My brain was not willing to cooperate with that endeavor. -- Kevin Bruceville, TX What's the definition of a legacy system? One that works! Errare humanum est, ignoscere caninum.
Jim Snellen All Messages By This Member #61 Funny you mention rewriting to Assembler Harold, that’s what I did and the DTFIS macro assembled just fine. Thanks for the feedback. Now I’m gonna look at the System Control Statements to refresh my memory on ISAM JCL.
